Augmented Reality as a Research Tool, for the Knowledge and Enhancement of Cultural Heritage

Starting from a reflection on the new role of digital technology in this pandemic situation, and partic-ularly the role of AR for Cultural Heritage, this paper presents two AR applications. The first is used to share the analyses carried out on the Pantheon surveys realized between the seventeenth and nineteenth centuries. The second is about the illusionistic dome in the Church of Sant’Ignazio in Rome, realized by Andrea Pozzo. These two applications can display three–dimensional models superimposed onto images and original drawings, and also two–dimensional contents: the results of graphical analysis carried out on digital copies. The final aim of this ongoing research is to develop some AR multimedia content, linked to semantic concepts.
